I currently have an iPhone 4 and I just bought a Samsung Focus (out of contract on ebay). I want to be able to switch between the two phones periodically as I plan on doing development on the Focus. However when I put my sim card in the Focus I can only get Edge data. Does anyone know how I can get 3G without changing my data plan with AT&T?
i think its something to do with the IMEI of your phone if ATT only have the IMEI of your iphone it will connect w/o a problem but if you swap phones, ATT's network will have a bit of a fit on your focus(it only concerns data though and it doesnt affect voice calls). if you want to use the focus you'll have to phone att support and tell them u wanna use the focus they'll ask for the IMEI of that phone and add it to their system and hopefully problem solved. sort of like your MAC address on your network card and i meant sort of.
