I signed onto an iPhone contract with Bell yesterday, the student plan for $55 and I so far LOVE THIS PHONE. It's everything I want and more. 1: First of all, if anyone has Bell as a carrier, can you tell me if the student plan has unlimited social network for the iPhone? My online bill says so, but I activated the phone through Best Buy Mobile and the sales rep didn't mention it, but the Bell brochure says so... 2: I've used approximately 75MB of a total of 1GB of data (by checking Usage on my iPhone) so far. Can you tell me if things like push on email and Facebook notifications will eat up my data supply? I seriously don't wanna push it, since my parents are offering to pay the first few months. 3: If I go into Airplane Mode, can I still receive texts and phone calls? 4: If I call Apple and complain of reception issues, will I still get a case? I read this on Wikipedia for the iPhone 4 page: The company has offered all customers a free case until September 30, 2010, or a refund within 30 days of purchase, as cases have been shown to correct this antenna problem. After this date, customers suffering these problems will still be supplied a free case (at Apple's discretion), by calling AppleCare.
