Those of you who are rocking an HTC Rezound from Verizon and are power users probably know that there was no shortage of Ice Cream Sandwich leaks. The latest is version 3.14.605.5 with build date of April 28 and it brings some improvements (and some drawbacks).
First of all there are updated radios in the leak. Then there are your usual improvements (as reported) like the lock screen shortcut settings that are now separated from launcher bar shortcuts, 3G/4G icon displayed prior to entering decryption password, messages application wrong sender displayed on occasion and IPv6 solicitation timer value change.
Now for the not so sweet part: the hidden menu, accessed by dialing the *#*#4636#*#*, has been removed. This means that the phone will no longer play nicely with AT&T or T-Mobile (and if you are using it on these carriers you might need to stay away from this leak, and probably the official update if it keeps the menu removed).
In order to flash this follow the source link for the download and make sure you are either running a stock ROM or you have S-OFF.
