Hi all, I have upgraded my T-Mobile Samsung Vibrant to Froyo (2.2). I don't really use a data plan and I am planning on getting it someday. However, I have one question regarding its 3G connectivity. If you go to Settings > Wireless and Network > Mobile Networks > Network Mode and you can see that you can only pick GSM or WCDMA. I need to connect to the 3G network using HSDPA, which I believe GSMArena said it can connect to. However, my phone seems to be telling me otherwise. So my question is, can my phone connect to 3G using HSDPA, or am I doomed to WCDMA?
