I had the iphone 3gs earlier this year and because of having to jailbreak and battery being awful I went back to the blackberry bold 9700. Now this iphone is looking much better, and I've been recently considering going to the android platform. So I have questions in case I want to make the move and buy the new iphone. With At&t changing their data plans, and as I have the unlimited data plan since January. 1. If I was to get the iphone full retail price and just switch sims card would I be able to use it and keep my unlimited data plan until my contract runs out? Dont forget I am currently using a blackberry bold 9700. 2. Any advancements with google voice and the iphone. I use this so much everyday. 3. Now that flash is pretty much dead on the iphone, what do you guys do with sites that require flash and there are quite a few of them and entertaining. Any way to use another browser to view flash on the iphone? These are just questions to help me decide. TIA.
