I picked up an iPhone4 when I got back from Madrid. I’ve been pleased with it. The much mentioned ‘antenna issue’ can be reproduced easily, but a case solves it easily and it doesn’t cause me any issues in day to day operation.
If you’ve been reading this blog for a while, you’ll have seen me mention iBCNU an APRS client for the iPhone. I hadn’t really tried it on the iPhone4 before today, other than swapping some quick messages at home.
The GPS in the iPhone4 seems to lock up on a position much quicker and I found that in conjunction with iBCNU it worked really well from the train in tracking my position and displaying the speed. Top speed on the way in this morning was 125MPH (200KPH), just to the east of Slough. You can see the track on http://aprs.fi – just search for G4VXE-6 – or I did a screengrab a bit earlier.
