Ok, I've been thinking about selling my iPhone 3G for about the past month and I think I'm gonna do it now that school for me is almost done (it's finals week!!). I didn't want to sell my iPhone before because my iPhone is a necessity at school. Now that it's almost summer, I can live without it for a while. Anyway what I'm thinking of doing is putting my SIM card in a $30 Samsung PAYG phone (saw one at walmart the other day) and then removing the data plan. Will I run into any issues if I do this? Also, I want to upgrade to the new iPhone whenever it comes out. Do you guys think I will run into any problems then? Will they be able to port my number and text plan over to the new iPhone, etc? If it matters, I'm not on a traditional iPhone text plan. I have a promotional plan that's 750 txts for like $8.
