Earlier this year, we took a guess as to which iPhone 4S rumors would come to pass. Though the phone ended up being called the iPhone 4S, we still got most of our predictions correct! Here's a recap of what we got right, and one we got wrong.

1. It will be announced on Oct. 4 — True that! The iPhone 4S announcement happened on Tuesday, Oct. 4, in Cupertino.
2. It could have voice control — Reports of an "Assistant" feature indicate voice activation that will allow users to make appointments, get directions, and set reminders as well as send SMS and iMessage texts just by speaking commands. Siri is that assistant!
3. It could be released on Oct. 15 — France Telecom's CEO announced to the press recently that he's been told the iPhone 5 will be released on Oct. 15. Though this was one day off (why would they launch it on a Saturday?), we thought the 14th was a more appropriate day.
4. It could be available on Sprint — Very true! The iPhone 4 and 4S are both available on Sprint.
5. It could come with a better camera — Indeed the iPhone 4S comes with an 8MP camera, just as expected.

And the one we got wrong:

1. It could be slimmer, wider — Several leaked cases (and case images) seemed to suggest that the iPhone 4S could come with a new form factor, similar to the iPad 2. Though this is not the phone that was announced earlier this year, we have a sneaking suspicion that these cases are indeed for the upcoming iPhone 5.

Still debating whether or not to spring for the new iPhone 4S tomorrow? While it does come with some shiny new hardware (and software) inside, not everyone will benefit from an upgrade. Debate no more — here, the pros and cons of the new smartphone, complete with a verdict on who should buy it and who should skip it.

Pros

• New camera — The 8MP camera with simple editing features (crop, rotate, enhance, and red-eye reduction), a backside illumination sensor, and larger aperture (for better low-light and white balance correction) make the iPhone 4S's camera one that competes with regular point-and-shoots. It will also come with face detection and image stabilization and the ability to capture HD 1080p video.
• Faster processor — The custom A5 chip in the iPhone 4S is the same one you'll find on the iPad 2, which means the iPhone 4S will be faster in processing speeds, games, and downloads.
• More carriers — Since the iPhone 4S is compatible with CDMA and GSM cellular bands, you can use it in more places around the globe. Even on Sprint's network, if you're looking for a change.
• Siri integration — Apple's new Assistant feature basically turns the iPhone 4S into a voice recognizing personal assistant. The demo during the keynote was impressive and highlighted some interesting uses for the blind, hands-free texting, and more.
• Wireless syncing — Raise the roof for wireless sync! This will be an iOS 5 feature that will be compatible for the iPad and iPod Touch as well, but I couldn't help but mention the fact that you'll soon be able to set up your devices and get updates without connecting your iDevice to a Mac or PC.
• Airplay — If you've got an Apple TV, the iPhone 4S will allow you to stream what's playing on your device to your HDTV with Airplay, which is built right into the new iPhone.
• Fingerprint resistant — The iPhone 4S has an oleophobic coating on its glass exterior, making it resistant to fingerprints by repelling oils in your fingers.

Tomorrow is the day! The iPhone 4S is one hot item, selling over a million devices so far, with lots more hungry Apple fans ready to wait it out in line to get their hands on the latest Apple smartphone. If you didn't get a chance to preorder the 4S, don't fret — there are still several more options that will allow you to get the 4S on launch day. Check out the list below, and start planning your attack!

• Apple — No matter which carrier you're going with, the Apple store will be stocked with iPhone 4Ss from all wireless providers. Doors open at 8 a.m., but be prepared for long lines and wait times. I suggest packing a lawn chair, sunscreen, and an umbrella, and maybe even a friend so you can make coffee and sandwich runs.
• AT&T, Verizon, and Sprint — All three wireless carriers will be selling the iPhone 4S on Friday, with preorders getting reserved handsets first. Store hours vary by location, so check with your local store to make sure you're in line early!
• Sam's Club — Members can preorder an iPhone 4S through Sam's Club (memberships start at $40 a year) while they're available, and your device will be held for you at the store. Open sales of AT&T, Verizon, and Sprint devices will take place while supplies last.
• Radio Shack — Past years have proven that Radio Shack may not get a lot of phones in stock so you might be taking a risk by heading here. However, getting in line early will definitely help your chances, and they'll be stocked with devices from all three wireless carriers.
• Target — Target will be selling iPhone 4Ss from all three wireless carriers. You can even trade in your iPhone 4 and put the money toward the purchase of a new 4S!
• Best Buy — Best Buy will likely have plenty of iPhone 4Ss on hand, but be sure to get there early to make sure you get a device from the carrier of your choice.

We're just days away from the iPhone 4S launch, and if you've finally decided to take the plunge and upgrade from your year-old iPhone 4, don't worry — there are ways for you to trade up without having to sell your iPhone online. These outlets are trading iPhone 4s for cash, so start planning accordingly.

• Apple — Apple is offering up gift cards in exchange for iPhone 4s in working condition. Exchange values will vary depending on scratches, battery charges, and whether you've supplied the power cord.
• Nextworth — Get cash for your iPhone 4 through this company that accepts phones via mail and sends you payment via PayPal or check.
• Target — Target is also working alongside Nextworth to offer customers trade-in values at their mobile locations or online and payment in Target gift cards, which can be used to buy the new iPhone 4S in store.
• Radio Shack — The Shack offers in-store trading in exchange for cash value, or you can choose to complete the trade-in online, which will garner you a Radio Shack gift card, which you can use toward the purchase of a new iPhone 4S.

Want an iPhone 4S, but don't want to be stuck in a contract for the next two years of your life? You're in luck. Apple's iPhone 4S product page shows that you'll have the option of grabbing an unlocked iPhone 4S in November.

You can choose from all three available models — 16GB ($649), 32GB ($749), and 64GB ($849) — but there's one catch: the unlocked versions only come with a GSM chip, which means you're tied to AT&T or T-Mobile (Verizon and Sprint use CDMA) in the US, but are free to use other GSM wireless providers across the globe as well without a contract. World travelers, this one's for you.

You'll soon have more options when deciding which wireless carrier to choose from if you're grabbing up a new iPhone 4S. Sprint officially announced its iPhone pricing plans today, making it the third provider (alongside AT&T and Verizon) for Apple devices. You can preorder an iPhone 4 now and the iPhone 4S starting tomorrow, Oct. 7, and both phones will be available on Oct. 14 or 15, depending on availability. Preorders will only be taken online.

So what about pricing? Sprint is the only carrier of the three to offer unlimited data plans. In fact, for $79.99 a month, you'll get 450 minutes of talk time, unlimited data (including web browsing, email, apps, and GPS), messaging (including SMS, MMS, and video), plus free calls to any mobile in the US, no matter the carrier. If you want more voice minutes, you can upgrade to a 950-minute plan for $89.99 or a "Simply Everything" plan that gives you unlimited voice, messaging, and data for $109.99.
