Samsung, Android, and Boost

So, I got this phone.  It seemed like a dream come true.  Boost mobile unlimited everything for $50 a month.  Android OS.  I guess I didn't do enough research.  First of all, Boost doesn't have coverage worth a shit.  I practically have to stand on the roof to get a signal.  Second,  the memory on the phone isn't enough to hold the apps I want even moving as many of them as possible to the SD card.  Third, the phone came with a bunch of apps I don't want and can't uninstall.  Now, it tells me that the memory is full and I can't receive text messages even though I have 19 MB free.  WTF!  The phone is a Samsung Galaxy Prevail.  Steer clear of that phone.
