I want to purchase a new (maybe used) unlocked quad band cell phone that is reasonably priced from eBay. I am looking at a Motorola Razr, Krzr or Slvr. T-Mobile sells the Razr and Krzr so I am thinking I should purchase a product that T-mobile already uses. The Slvr is not sold thru the provider so I am worried about compatibility. On eBay some stores offer phones that are flashed/synced with T-mobile for extra cost if I would like to use MMS. This would allow me to send picture msg and view the Internet. But someone at T-mobile advised that it sometimes doesn’t work well. So basically, should I buy an unlocked phone that I know T-mobile uses? And if it has MMS should I have the eBay store flash/ sync to T-Mobile or can T-mobile do it for me? Also, if the phone is from Europe will it be different and problematic to use in the US? The reason I don’t want to buy from T-Mobile directly becuz they would charge me full price since I cannot upgrade for another year. PLS HELP. Thank U.
