XDA 2 phone calls - pickup delay

[usall5]

Could anyone help please? I have searched and searched to no avail..
I have the xda 2 and have had all sorts of problems running some software but the phone part appeared to be ok !?
I can now run all the things I want and they work,usually, ok. However the phone is now getting so bad it is beyond belief.
If I do receive calls I cannot answer them - well this is what I thought for the first few weeks. It now appears that I have to just keep saying "hello, hello, hello" until I can hear the calling party. I used to hang up because nobody appeared to be there.
I thought an radio rom upgrade to 1.19 may be the answer and tried (4times) to do that: I click on the HimaUpgrateUtHTC and away it goes...but it disconnects the Activesync connection, does not reconnect and then comes up with the error connection code 101.

1. Will the upgrade cure my phone probelm - if not , any other suggestions, please
2. How do I upgrade only the Radio when the Activesync connection is shut down by the process?

Thanks for all guidance.. Great site by the way.

No replies, so I moved on myself -
Info' for all out there, as it may help someone, below.

I found that if I did a complete redo that the Activesync did not go off. But phone problem persisted. Search all over again and found an incling that BTHTools1100 may be the culprit/adding to..
I have uninstalled BTHTools and soft reset and the phone works much better now... Apparently the Bluetooth had to come on before the call could be answered....
I had this on before and did not notice any probs though, so ??
I now have to switch on bluetooth manually before using sat nav whereas before BTHTools did that automatically.
Anyone any ideas on how to set up so phone and sat nav work correctly? That is doesn;t come on for ohone but does for sat nav.
