I have the following devices as stated above. I would like to make a phone call from h5455 using pocket phone tools, which connected to my T68i using Bluetooth, then I associate my Bluetrek G2 Bluetooth headset with my T68i.

My intention is to keep my phone in my bag and just use the IPAQ to dial and talk through the Bluetrek G2 headset. I know that the headset is not supported in IPAQ. Can the T68i associated with two Bluetooth device, one with Bluetrek G2 headset and another one with IPAQ 5455? T68i can work independently with H5455 and Bluetrek G2 headset but not both at the same time.
Hope someone can give some suggestion. Thanks for any help!

Current devices they don't have multiplexing to keep more than one device connected al the time, you will have to turn them on passive mode.

Using Running Voice GSM with this combination it will be running in Passive Profile. It will only detect sent SMS messages and phone calls made from Running Voice GSM. Incoming calls are not detected and SMS messages have to be manually synced to the Box Manager. Running Voice GSM is not able to display signal strength, missed call or other phone display icons while in passive mode.

Reference to Pocket Presence:
"Passive Mode is developed to enable you, the user to utilize a BlueTooth headset in combination with a BlueTooth equipped GSM/GPRS handset from Sony Ericsson and a Pocket PC 2002/Windows Mobile 2003 device.

There are currently no Bluetooth chips on the market that are able to support manifold connections to 3 devices simultaneously; they only support peer-to-peer communication. This means that you can only be connected via Bluetooth using any of the following combinations: BT GSM/GPRS Handset - BT Headset· BT GSM/GPRS Handset - BT equipped 2002/2003 PDA and Running Voice GSM· BT GSM/GPRS Handset - BT Headset – Running Voice GSM in Passive Mode"
