Does anyone know if this phone can be used on MetroPCS? It looks like this phone uses WCDMA 850 / WCDMA 1900 and MetroPCS is CDMA 850 / CDMA 1700 / CDMA 1900. I do not know enough about this technology to know if CDMA and WCDMA are compatible. Also, if it is compatible, would everything work such as web, picture messaging, etc? I plan on taking it in to let them look at it, but the wait in their store is typically about an hour, so I am hoping for some information before I go in there.
