Danger Hiptop 2 / Sidekick II

Ok so like yeah sidekicks are cool and they have the full aim and t mobile has unlimited texts. I have verizon and i end uppaying like 110 bucs just for my plan alone becuase i go over on texts by like atleast 50 bucs a months haha ( my moms plan is like 40) now is it worth it to go to t mobile because i would be saving money wiht the unlimited texts and the aim is like amazing.. but tmobiles service is sooo bad my friend even jsut told me how much it sucks and is it worth it just for the AIM and unlimited texts... please advice
