Saw a reference to PassPack today in today's (June 14, 2007) Chris Pirillo's Picks. Would I use that free service? Think about it ... you're giving the passwords to a free service ... does that make sense to you? Having run an Internet operation and seeing what can happen at various operations centers, I think I'll pass. I know, I'm probably in the minority here. I mean, it's soooo convenient, and they publish their privacy rules and practices and they swear that your data will always remain encrypted and and and. And that's all well and good until it's not. And then where are you?
I'm sure the service will flourish and go on to make its founders hundreds of millions of dollars and all of the passwords will remain safe and encrypted. Like the debit and credit card data at T J Maxx?
You can always go to Wikipedia -- their UMTS article describes it pretty well and there's even a set of links on the right side of the page that will take you to other standards. Aside from that, here's an article from a completely different site that, while it talks about Cingular in particular, is still a fairly good intro to UMTS and HSDPA along with their speeds.
