how to keep device ID always same

Hi,

i flashed my device most frequently, but for that i am in trouble for my office mail client [IBM traveler]. every flash the sever treat my same device as a new device with a new ID. So mail can not be sync and traveler cant get connect with the server.

is there any way that i can keep the android id same ? even i flashed different ROMs ? pls let me know cz i am stuck in same rom for a moment due to this issue

[i.e Device ID: Android_861579df9dca07ca ]

thanks/ toufiq
