Is HSPA+ (3G)?

[waloshin]

My area the local network is going from Cdma to HSPA+ so I was wondering would any 3g device that is unlocked work with this HSPA+ such as a HTC Desire?

Or is HSPA+ a different type of network?

HSPA+ is 3.5 or 3.75G. It is HSPA's evolution and a pre 4G technology. Also it is GSM oriented.

Evolutions
2G - GSM
2.5G - GPRS
2.75G - EDGE
3G - UMTS/WCDMA
3.5G - HSPA
3.75G - HSPA+
4G - LTE

HSDPA+ is 3.5G - it's halfway between 3G and 4G (LTE).

So being 3.5 a 3g phone wont work?

As far as I know, as long as the device supports the frequency, a 3G device will work on any generation of 3G. From a lowliest of cheap USB 3G cards to the iPhone 4 on the same tower. And if you bought it in the same country as you plan on using it, the frequencies should be the same.

If the phone is 3G (ie HSPA support), then it must carry GSM/EDGE support when 3G is not around. Same is said for it's HSPA+ abilities. All phones have a fallback solution.

However, if the network is 3.75G exclusive, in other words, the network provider only built a HSPA+ network with no fall back support, then yes, it might not work.
