   "The first step required to upgrade WCDMA to HSPA is..."

From all the reading I have done, which makes me feel like a dog chasing it's tail..
 - wcdma doesn't imply HSPA support, but HSPA *can* be backwards compatible with the older specs.
 - Edge is a competitor to (wcdma based) UMTS
 - Edge runs inside existing GSM freq, while UMTS required all new bands

I am sure Rick will correct us  ;), but sounds like your device is too old and is falling back to now legacy EDGE (pre-3G) frequencies because T-Mobile is busy upgrading their (UMTS, using wcdma) towers and aren't looking back.

How old are the devices, or rather, how old are the chipsets in them?

So a wcdma 3g phone shud get 3g & hspa+ on T-Mobile service? BC I'm only getting edge. But same Sim in another phone gets hspa+ & 3g.
