Same here. My data cuts in n out, each followed by that 'IMSFramework is not responding' prompt, after which my data resumes once I confirm to close the troubled service.
I'm wondering if this is related to any 3rd party software we have running. I'm rooted, have CPU master enabled, rom manager, titanium, adaway, and of course superuser. running 4.0.4 with verizon. that's basically all I have concerning root. Anyone else share similarities?
