If your serving Node B is HSDPA and HSUPA enabled, it should show 3.5G. and your serving cell is not HSDPA/UPA enabled, it shouldn't show 3.5G. This is perfectly normal.

Remember, with Release 99, you can only get downlink speeds only upto 384 kbps whereas with HSDPA enabled, you can get speeds upto 14.4 Mbps (without DC/MIMO).

And yeah, this is the theory part.
Thanks. Anyway I don't care if my phone shows 3G or 3.5G. I only want to have a stable connection, and it seems that in big cities (where 2G,3G 3.5G nodes co-exist) the intenet connection freezes when auto-switching from 3G to 3.5G and then back again after an inactivity period. By the time being, the only workaround is to use the 2G network, which works OK in big cities, but is very slow.
