    Hello,
    I am using an iPhone 3g (which is doing terribly right now- it barely functions). I bought a curve 8520 and I will unlock it. Can I keep my current plan on AT&T? Also can I switch back and forth between the two phones with the same sim?

    Thanks,
    Paul

    Yes, you can use the 3G Sim card with a Blackberry...
    All you need to do is to unlock your Blackberry and it will be able to work with other carriers.

    So, just use some Blackberry unlocking service and then you are free to use your Blackberry phone with your old Sim card..

    Yes you can but AT&T might change your iPhone Data Plan to a Blackberry Data Plan. If you're on the grandfathered unlimited they will keep you on unlimited but for Blackberry and you can always switch back to an iPhone.

    Yes there may be some complications considering those phones are very different

    With AT&T as long as you're on an unlimited data plan, you can switch back and forth to other smartphone plans and will keep your unlimited.
