I haven't yet updated to ics because of all the issues. I believe most have been fixed with the 6.1.a2.45 firmware release. There may be some minor issues left but I could live with that. I just want to make sure the data problem has been fixed because that would be one problem I couldn't live with. Thanks for your help.
It seems that the .45 update fixed the data sleep problem. I have not experienced any problems with 3G or data running on .45.
