I just woke up bleary eyed to another email from Secret Agent 711 who just put up OS 188.8.131.528 for the 8220 Pearl Flip. The 8220 does not see that many OS leaks so this may be worth a go if you have one.
Let me know what you find in the comments and keep the tips coming!
NOTE: Do not install this software if you do not know what you are doing. It may make your BlackBerry FUBAR or just plain angry.
