I don't have HSPA+ equipment I have an N900 with HSPA only and my contract is capped anyway. HSPA+ is 4G, it was allowed to be called 4G because it was an improved network that could still compete with LTE and WiMax. here is a speedtest in Finland with HSPA+ http://www.youtube.com/watch?v=6XfG9...eature=related If you want to know about the improvements in HSPA+ over HSPA. http://www.qualcomm.com/common/docum...and_021309.pdf
The following standards are typically branded 3G: the UMTS system, first offered in 2001, standardized by 3GPP, used primarily in Europe, Japan, China (however with a different radio interface) and other regions predominated by GSM 2G system infrastructure. The cell phones are typically UMTS and GSM hybrids. Several radio interfaces are offered, sharing the same infrastructure: The original and most widespread radio interface is called W-CDMA. The TD-SCDMA radio interface was commercialised in 2009 and is only offered in China. The latest UMTS release, HSPA+, can provide peak data rates up to 56 Mbit/s in the downlink in theory (28 Mbit/s in existing services) and 22 Mbit/s in the uplink.
