I forgot to say ... on all Android models it is not yet possible to connect a heart rate monitor because Android does not yet support the Bluetooth Serial Port Profile (SPP).
My girlfriend is planning on buying a HTC Tattoo which is running on the Android OS. This phone supports just a low-res 240x320 pixels and having read several reviews it has become clear to me that most of the apps on the Android Market won't work (yet) because of this low resolution.
Can anyone tell me if Run.GPS runs without problems on the HTC Tattoo?
