On a another thread i complained about sgs navigation and how it wasn't working. i was told to turn on data mode, i did and now it works flawlessly.
On a 30 min journey this morning lock on time was instant, rerouting takes less than 5 seconds (driving at 50-60 mph) and my position was 100% accurate through the journey. all this AND using satellite imagery at the same time with pin sharp images on the screen. This is way better than my bog standard sat nav.
I bought the phone from Tesco, which uses 02 uk in jan and upgraded to froyo 2 weeks after i bought it.
So fingers crossed it continues to work like this
