I have used aerize, and peekaWho, and now use message peek...and I gotta tell you that Message Peek has it over both those apps. It gives you a full screen shot of your email or SMS for the allotted time you select. I've been using for about a week now and it has beeen flawless. Check it out...very nice clean app...that works GREAT. You can get it right here in the CB store. $7.99..and I think it comes with a free trial...Ilike it better than both peekaWho and aerize...easy.
