Well I'm sure by now you have heard the latest Smarthphone Experts Roundtable Podcast! (If you haven't had a chance to listen you better get on it, great podcast!)
You may have heard our very own fearless leader, Dieter, chime in on one thing that he hates about iPhone 3G, the fact that you can not turn on Wi-Fi while the radio is off (in Airplane Mode). Or so Dieter thought. You can indeed turn Wi-Fi on while the radio is off! And doing so is a snap!
Now you can enjoy browsing the internet, checking emails, or anything else data related all without the radio on!
[Ed: Thanks also to Stephen Sizemore for bringing this up in the podcast comments! Let us know how that works for you, b'okay boss?]
