I currently have an unlocked original LG Chocolate (KG800) GSM cellphone that I'm using with Cingular. Needless to say,the bluetooth functionality sucks when paired with my car. The bluetooth connection connects about 75% of the time and the only thing that works is speaking through the speaker system and using the steering wheel button to pick up phone calls. I can't dial phone numbers from the car and see current battery life or signal strength.

Can anyone recommend a good Bluetooth cellphone from Cingular (GSM)? Basically just a good solid BT cell to pair with the car. This is the criteria:

1. very clear (strong signal strength)
2. good BT connection with the IS250 (reliable connection each time)
3. full BT functionality from the car (phone book, number pad, shows signal/battery bar)

 

here is the lexus site, it tells you what phone/carrier is compatible with the IS250/350

I have an iPhone, and it seems to work great with the IS. No problems with signal strength, it syncs up a few seconds after I start the car, and shows the battery bar. It also shows caller ID when the phone rings and all that good stuff.

Before the iPhone, I had the Samsung Blackjack. That was a piece of crap. No integration what-so-ever with the IS other than headset usage.
