Samsung SCH-i760

PDA phones require a data feature to be activated. that could be unlimited data for $45, 10MB for $25, or the pay-as-you-go data service which is a free feature as described above. Blackberry's don't have a pay-as-you-go option by the way. Once the phone is activated the pay-as-you-go feature can be removed and a data block put in it's place. i know text can be used with the data block in place but i believe josiah was correct in saying that mms would be disrupted. as for the software updates, some of these are done through external sites so wifi should work fine. the get applications feature won't work with the data block on, but you should be able to surf directly to the site and download from there.
