I just got my iphone yesterday and for some reason i can't receive text messages from nextels and they dont get any text messages i send them. And also today my mom sent me something(t-mobile) and i replied and she didnt receive it. i don't know if since my number was original from nextel if that has anything to do with it or if i just need to give it alittle while. Any help would be appreciated. And also will there be an update with an application for aim? or what is a good site to use aim?
