What exactly are the data plans? Are they like sending messages?
Btw I found a 8Gb iPhone near my place for 350$ with FW 1.1.2. How does that sound?
Sounds good. Get it.
A data plan is a service that you need to subscribe to if you want to use some features of iPhone when you're out of range of Wi-Fi.
For example, Google Maps, Stocks, Mail, Safari (Web browsing) and YouTube.
If you want to be able to send and receive mail any time, you need a data plan. The one I had from Rogers was $60 a month which gave me 25Mb of data transfer a month. With careful usage, I kept under my 25Mb a month, but I had to be really careful. After you reach 25Mb, they don't tell you or shut it off, you just get billed $9 per Mb after that. This can add up *really* quickly. And the only place you can see your usage is on iPhone itself.
To the other people that say it's great without a data plan, I 100% agree with you. It's a fantastic piece of technology and I am completely spoiled by having had one. All I'm saying is that as wonderful as you think it is now, wait until you can get unlimited data. Then you'll see iPhone's true colours. It's ultra-fantastic when you use it with unlimited data (which is how it was designed).
But for $350, yep, get it. You definitely won't be sorry. Just watch your data usage if you spring for the plan.
Cheers.
