I was going to buy a Blackberry on Ebay, will it work with my Nextel sim card? Also, I see that it has wireless internet capabilites. Can you just connect to a wireless network (Wi-Fi) or do have to purchase a data plan. thanks in advance.I have a Nextel i560 and want to put that sim card into a Blackberry 7510. Will it work. And can the wirelss internet connect to a Wi-Fi network without purchashing a data plan?

It would help to know your zip code and the model of blackberry you're thinking of buying, but lacking that, if you buy an IDEN 8830 or 7100i, it should work.Note that it is critical that it is IDEN if you want it to work on the Nextel network. However, any CDMA blackberry such as the 8330 or 8703 (if you can find one), will work on the Sprint network.
