TT920 Can't/won't see iPhone 3G

[mfsunshine]

As the title says my TT920 can't/won't see my iPhone 3G. The iPhone is set to discoverable.

The iPhone can see the TT920. It recognizes it on the phone's end. When I try to pair from the iPhone side it prompts me for a "pin". I tried the standard "0000" but to no avail. Any one have this problem before? What pin shoul I be using?

Any solutions out there?

Thanks.
