So yesterday I finally bought myself an iPhone(yes I know the 3Gs is coming out next friday, but none of the features really stuck out to me, and I got this one cheap ), so I have a couple questions. 1. TomTom is releasing a turn by turn GPS app at some point, and I'd love to be able to use it, but I got this iPhone with no data plan(I'm in Canada), so will an app like that require a data plan? Does using the GPS at all for any app require a data plan? 2. When 3.0 is released on Wednesday, the update includes MMS. With an unlimited SMS plan from Fido, will that include the ability to send MMS? 3. I've heard that with Roger's you can call and have them put a data block on your account so that you don't accidentally use data, and be charged ridiculous amounts for it, can you do the same with Fido? If not, is there another way to do this? Thanks in advance!
