tmobile prepaid?

is it even worth it. what are the rates

It's probably the Best deal in prepaid. Once you pay them $100, your expiration is one year and refills are as low as $10 a year to keep it active. At the $100 level, minutes are only .10 each and increase slightly with smaller refills. Romaing over most of the US and there are a handful of web sites that you can access free...really.

How do I get a prepaid sidekick???

have you tried to go to walmart, target???

Walmart & Target don't sell Sidekicks. Actually I haven't seen any Tmobile prepaid phones at those stores, just the cards.

Have you looked into Flexpay?
It's just like prepaid and postpaid. You get the same benefits of postpaid except you pay in advance like prepaid.
There is a 2 year contract which you would get the discount price or you can do the month to month but would have to pay full retail or you could buy a previously used phone through craigslist or eBay
