Welcome. Just get a cheap pay as you go phone or buy a used 3GS off Craig's list to use for the next few months. Trust me, you'll be kicking yourself if you tie yourself down to a two year contract with an old model.
Welcome. Will this be your first iPhone?
Yes, it will. I'm pretty excited!any tips? lol
and thanks for the advice, everyone, still debating
Because the 4S will suddenly stop working when the next one is released?
If it's your first apple device be prepared to be blown away. I went from only ever using windows, to an iPad, and I haven't been on my pc for over 15 minutes at a time in the past 2 years. It'll be great, whether you decide to wait for the latest hardware, or treat yourself early.
