Even though 4.0.2.A.0.42 rolled out since October through SEUS or PC companion. But from my experience, OTA update is the easiest way to remain rooted. It works for the third time now since 2.3.2.
My phone popped up with 4.0.2.A.0.42 OTA update available few hours ago.
Previous Firmware: 2.3.4 (4.0.1.A.0.283) rooted
Update path : OTA through 3G
Duration : Around 15 minutes.
Steps on updating is easy: tap on notification-> download-> install it. It will be done automatically with all contacts, data and preferences remain.
New Firmware Notification & 4.0.1.A.0.283

i) Latitude Icon changed
