Often times I find myself running around with my laptop and needing an Internet connection. I've hooked up to the public WiFi networks around; a good option when they're there. I've had the Verizon WiFi card; a costly, but decent option. But about a year ago, I found the very best option around ... are you ready ? /insert drumroll sound here/
It's PDA.net through my Smartphone! PDA.net is an app available on the Android, Blackberry, Palm, Windows Mobile, and if you jailbreak your IPhone, you can get it on there too. It is one of the best practical apps out there. You can get it through the marketplace or at JuneFabrics (no, it isn't a fabric store).
I used the free one for a while, but quickly upgraded for less than $25.00 per year so I could view secure sites. I've even changed phones and it upgraded with me. I like it when they take care of things like that.
Recently I found a public WiFi network to be too slow. So I hooked up PDA.net through my Android with it's USB cord and PRESTO! I could get my work done online and even held a webinar for about 30 minutes from my phone!
