A lot of people have reported poorer first-lock times with GPS after the 6.1 update, unfortunately. Some seem to be unaffected, for others it's a real issue. By first-lock I mean the first time you use the GPS after a soft reset, or after several hours.

You might want to check which radio version you have - the "original" HTC update came with radio 1.65.16.25, but more recently they snuck out another version of the same ROM, this time with radio 1.65.17.56 (both ROMs had the same base version you quote above - 3.28.405.0 WWE). I noticed a definite improvement with the newer radio, although it's still not quite up to 6.0 standard - definitely usable though.

For lots more info on radios and how to update yours, see here - http://forum.xda-developers.com/showthread.php?t=393182. To find out which radio you have at the moment, go to Start -> Settings -> System (tab) -> Device Information and check the radio version listed there.

As I said - I've received it (or rather - came back from Greece) last Friday and up until now 3G stability is good.

Did you fiddle with VoIP on Kaiser at all before that problems started to happening? What applications did you install recently?

My test was quite simple: T-Mobile's sim card in Kaiser, 3G coverage, place a call, beep-beep-beep straight away - three times a row. I take sim card off Kaiser and put into Nokia E61 - 3G coverage, place a call, connected - three times in a row.

At the same time, the other sim card (Polish sim on roaming in T-Mobile UK) - placing calls in E61, no problems. Swapped to Kaiser, and beep-beep-beep again.

I might try Vodafone or any other UK-based operator sim card in the evening, before I actually do hard-reset (I really hate to do this!).

Since last few days I have noticed my Kaiser has serious problems with 3G coverage. Basically, when phone's band mode is set to Auto or WCDMA, I virtually cannot place any call, or use data. It works sometimes, but very rarely and unstable. I usually get 'beep beep beep' drop when try to place a call. It also searches for 3G signal quite looong time, before it actually use it after rebooting phone. When I switch to 2G - everything works perfect!

Initially I thought it's a network related problem, and even called T-Mobile's tech department, but guy said they have no problems from their end. So I did further investigation, and found out that my other 3G-enabled mobiles are working properly with T-Mobile's 3G, so it turned out to be actually problem with Kaiser itself. I've uninstalled applications that I installed recently - no luck. I've also noticed I still have 'Internet' tab in Phone settings, although I've uninstalled all VoIP-related applications quite a while ago, and now I can't see a way to get rid of it completely. But again - could VoIP traces be a problem for 3G specifically?? :-o

I'd rather avoid doing hard-reset to find out, so if anyone else have experienced similar problems with 3G in their Kaisers, or maybe you know how to remove VoIP remainings from the system - please reply. Thanks.

Have you tried getting your initial fix with QuickGPS? That's what worked for me. Once I used that, I haven't had any problems with TomTom getting a fix but it seems that I usualy need to get a fix with TomTom first before I can use Google maps.

dt11, where did you buy 6gb microsdhc?
