I wasn't trying to prove anything by saying I work in IT; so please don't use a condescending tone with me, a loyal member of this community.
552 error happens to me, like I said, after most application installs...sometimes it happens sometimes it doesn't. It has happened and has not happened after BBM5 installs, Yahoo! Fantasy Football 09 installs, and Facebook installs. I have wiped the devices and installed with no apps, MANY TIMES. Eventually it happens again....
I am a frustrated user venting to a community of people who have teh same device as me and my or may not be experiencing the same issues, and hopefully finding a permanent solution.
