I had similar issues to what you are describing with yours on my original unlocked/unbranded HOX on T-Mobile. I had issues on top of the ones you mentioned where it was also saying I had a signal and had appeared to lock up and would just drop the mobile network and say at the bottomg of the screen "preparing sim".

Most the time I was stuck with putting it in and out of airplane mode to make calls, only for them to drop or fail all together.

This was on both 1.26 and 1.28 FW. In the end I took mine back and swapped it and the replacement has been perfect since. so it was without doubt a hardware fault in my case!

Good luck solving your problem, but I would suggest taking it back and getting a straight swap.

You can't change you ROM unless you unlock the Bootloader at HTCDev and this will void your warranty with HTC.

Three will release an update eventually, and 1.28 is no better signal wise for me than 1.26 was!!

Interesting, I too had the Preparing Sim message until I got a new SIM from Three, this seemed to fix this message but I am still having Signal Problems.

I think I'll follow your lead and go for a replacement, I have to use Airplane mode to force the signal to reconnect as well.

Thanks

I can confirm I have these problems. I'm on three but the phone was from Dialaphone and with orange but is unlocked. I have exactly the same problems as those been described. This is a very irritating problem that makes me miss calls and texts in my poor 3 signal area.

I think you're best off to return it for a replacement, that's what i'm going to do. Hopefully that will fix my problem and not create any more!!

I have the same issue on my device. On my 2nd replacement and its still the same.

No problems with my iPhone 4S.

Hopefully a radio update will sort this out.

If that is the case and you've had 3 replacements, maybe it's worth holding out for the next update to see if that fixes the problem.

I'm a little uneasy about returning it for a replacement as I don't have any other problems with it (bad screen seal, banding on display or yellow display) I may end up with more problems with a replacement.

I think it might depend on location, in some areas the 2G signal (Three use Orange network for 2G) has been turned off. In my Area (South West England) I still have access to the 2G GSM Signal.

Obviously Three save a lot of money from turning off GSM and not paying Orange to use their network.
