HTC Touch Sprint PCS Delete???
 

It's probably been done before, but I need to know how to delete the damn sprint pcs connection setting. Heres the problem. I have cricket, its flashed, wap works and everything else, but if I open another program, it goes back to sprint. Need a STEP BY STEP to delete the setting. Also, my phone says EV until i connect to the internet, reason why?? Thanks Guys!!
