My experiences with VikingTalk after one month. I'll start with a score of 10 and increase the score by 1 point for each advantage and decrease it by 1 for each disadvantage.

Installation: pretty painless, though confusing for non-techies. You have to install the app, then contact VikingTalk. They send an sms stating you have to remove any previously installed version and reinstall it. After that, you receive a second sms to activate your account.
After upgrading my iBrain to iOS 5, I had to repeat the entire process. So -1 for the rather complicated setup process.

Using VT over Wifi: All good as long as I have 3 bars of wifi. Any less will cause terrible calls with loads of hickups. No information seems to be available on how to optimize your wifi settings (QoS?) for VikingTalk. 0 points added/detracted.

Using VT over 3G: Good call quality from my side. Other side sometimes complains about call quality. +0.5

Using VT over Edge: absolutely impossible to use. -1.

Total score: 8.5

It's a promising application, but more info should be released on how to troubleshoot bad call quality.

Disclaimer: I suspect our Telenet wifi router to be absolute rubbish, but still, without any info on the protocols used/possible optimizations, it's very hard to draw a final conclusion.

Telenet recently changed their internet subscriptions again. The cheapest option now (when you want internet + digital television) is a Basic Shake, which gives you 20 Mbps and 50 GB download limit for € 31,95.
My current connection is BasicNet XL, which is 10 Mbps and 15 GB download limit. So changing to a Basic Shake would, technically, be an upgrade. Not so for Telenet, because it's € 4 cheaper, they consider it a downgrade, and if you want to switch, they charge you € 50 activation cost. Obviously when you switch to a more expensive option, they don't charge you anything. How much longer are we going to accept this?

And before you start flaming, copper is NOT an option where I live (4.8 km from the lex).

Panic in the smartphone world yesterday, as Pete Warden revealed the iPone stores your location data.
Obviously that's bad.

Or isn't it?

I copied the file /private/var/root/Library/Caches/locationd/consolidated.db to my laptop, and used the Firefox add-on SQLite manager to examine it. I only have one conclusion: even if this file gets sent somewhere (which is highly unlikely at this moment, as no evidence has been found), it's utterly useless. Records show I've been way beyond Metz in France. I can guarantee you I've never been there.
Every night I sleep at home (can be confirmed by my GF), and yet not a single record indicates I've ever been there. The closest I get to home, according to the records, is 1 hour from home.

For a clear understanding: I used the raw data from the file, not the Pete Warden tool.

Sorry to burst your bubble Apple bashers, but until proven wrong, imho this file is totally useless, and people are making too big a deal of it.
