I tried WP Mobile Detector and MobilePress while I was looking for mobile compatibility for my entire site. Not just my blog. WPTouch is the only 1 of the 3 that gave me everything I needed. I don't know code or anything like that and basically just wanted my site to work on mobile devices. And I have a Multisite install. I just installed WPtouch. Have tested it on a pc with IE and Firefox, an iphone, and a Windows phone. The results are beautiful. Very easy install.
