Issues in J2ME devices in using JSR 75 (PIM Details)

Hi,

I am working on a J2ME project, in which i am using JSR 75 (PIM APIs) for accessing and hence using contact details.

i am facing problem in getting the UIDs for phone contacts on some Sprint devices. These devices includes Samsung RANT and High Note. Please let us know if anyone has worked on these devices and has faced such issues.

Please note that
1. I am able to get UID for other devices like Nokia N 95, N81, Sony Ericsson 580.
2. Also this problem exists only on some devices which are mentioned above.

Please treat this as urgent and reply back at the earliest.
