Recently I got an unlimited data plan for my blackberry. So, first thing I did was browse around, wow, what an eye opener. Things took forever to load and display, often locking up the device.
This got me thinking about how adequate my existing sites are for mobile browsing. Searching around I found Mobiready to evaluate this without locking up your own device (assuming you have the capability to test on mobiles).
For example, this site in it’s current form has problems.

After that abysmal score you have a few options, using WordPress as I am, you can go on a plug-in hunt. Though if you’ve hand coded your site then Mobiready offers a list of things that contributed to your score and suggestions to fix it.
I have yet to fix any of my sites but I’ll update this post to see how well the suggestions help. I want to note though, any tools are just a tool, you still should test before you support any mobile access. (Yes this means getting a hold of a Blackberry, Android powered phone, Pre, and an Iphone).
