I'm looking for a pretty nice phone I can't get within my heavy $50 budget. This is my first phone so be kind on my choices.

I looked through and it came down to these:
http://www.t-mobile.com/shop/phones/Cell-Phone-Detail.aspx?cell-phone=Samsung-t219-Red -Free

http://www.t-mobile.com/shop/phones/Cell-Phone-Detail.aspx?cell-phone=Sony-Ericsson-TM506-Amber -Free (Except in red)

http://www.t-mobile.com/shop/phones/Cell-Phone-Detail.aspx?cell-phone=T-Mobile-Shadow-Black-Burgundy -Free

http://www.t-mobile.com/shop/phones/Cell-Phone-Detail.aspx?cell-phone=Samsung-t339 -$29.99

And I might go over my budget for this badass.

Now I need help choosing which one. :V
