GSM/WCDMA toggle


Hi I have a HTC Sensation and have problems getting a H signal at my home address.

My phone does get a sniff of one though which varies between 3 and 0 bars, mainly the latter and it chooses to try to get this signal rather than opting for a full gsm signal. This then causes problems when trying to make and recieve calls.

To get into the gsm only setting selection on my phone its a long 5 click process.

Can anyone point me in the direction of an app that toggles this instantly as the 3g aps dont do the job and my H signal still stays active.

Ideally I would love an ap that realises that Im home, disables my wcdma and switches on my wifi. Then when i leave home reverts back to wifi being switched off and re enables wcdma. I'd be amazed if there is an ap that does this but heres to hoping.
