Most likely your phone isn't really 3G. Real 3G isn't out yet. Even Docomo, who claims 3G, isn't TRUE 3G. What's out there now is 2.5G (GPRS, CDMA 1xRTT, etc..) In about a year and half, the carriers will upgrade to 3G(Umts, CDMA2000). BUT the carriers are advertising 2.5G as 3G to boost revenue stream NOW so they can pay for 3G upgrades.....
Also, 3G (at least UMTS) has a theoretical bandwidth of 2mbps, but will achieve far less under normal usage. Just like a cable modem or a regular modem won't normally get it's maximum speed. Count yourself lucky if you EVER get 2mbps on a 3G network.
Some people here have been getting confused about some things so let me clarify:
There is a difference between discussing a SYSTEM (GSM, UMTS, CDMA 1x, CDMA2000, Iden) and discussing it's RADIO ACCESS METHOD (TDMA, CDMA, W-CDMA).
For the record:
GSM: Uses the TDMA Radio Access Method.
UMTS: Uses the WCDMA radio Access Method.
CDMA: obviously uses CDMA radio access method.
A previous poster did a good job of clarifying how the different Radio Access methods work so I won't get into it.
The main differences between the different systems that use the same Radio Access Method (Umts and Cdma 2000) is architecture -- that is, how the system is structured and built, as well as the messanging that goes on to bring up and support a call.
So in talking about how "good" one system is vs. another, it really does no good to compare say CDMA2000 to UMTS. YES there will be some significant differences between the systems, but not in the way the information is sent on the air. If you want to talk about differences, talk about other things other than the Radio Access method.

ziemowit, how do you compile using gcc (details?)
and then how do you upload the app to the phone!
any help would be appreciated.
