Not too happy with Norton right now. Turned on my Samsung Galaxy SII yesterday morning, to the message of Norton "locking me out" due to " a new SIM card being placed within the device" (I never even changed it). My "paid" version switched to "lite", but, that couldn't even be used until I had my "significant other" unlock my device by texting me, which in some respects, I was glad to see actually worked for what I thought I had paid for, within a 1 year license. Problem is, restarting my device, after taking the battery out, still had the Mobile Security locking me out of my phone. I thought uninstalling, and re-installing the software would help, but, to no avail, as I guess having purchased thru the Android Market, did not recognize my previous license, and remaining 240+ days of paid license that was due to me. I have Norton 360 on my one remaining Windows laptop, and recently purchased for newly bought iMac, but maybe the Mobile Security was not all it was cracked up to be?
