From your other post:
Can you confirm what should be happening with the phone book plus does the app do anything with the power settings on the phone like turn off some services as one of the benefits of rSAP from what I've read it allowing the phone to use less power while in Sim Access Profile
The power saving is because the baseband software switches off the mobile radio unit while SIM access is active - at least that's what I observed on the HTC. After a longer connection you can check that with the new Android 2.3+ power consumption graphics: while the phone signal is off the curve should be flatter.
Regarding the transfer of the contacts: pay attention to a notification on your phone (usually with a sound) asking you to grant access to the phone contacts. This happens after the SIM contacts are read which may take a few minutes. My current state of knowledge is that the Phone Book Transfer Protocol (PBAP) gets better with every Android version. With 2.3.4 only the last dial, missed call, ... lists may have problems with non-ASCII characters.
