Speed improvements with 4.1

While waiting patiently (well, sort of) for the new update, I found this really helpful review and tests of 4.1 on the 3G phone. Three pages of good info:

I have absolutely no idea what that article is talking about with regards to typing speed. On my 3G with 3.1.3 there is no lag to my typing, no matter how fast I type. I have just tried tapping as fast as I can using two hands, on just two letters. no missed letters or lag. Its instant. Typing is perfection for me.

I have 6 pages of apps, I'm forever buying more, apps com and go off my phone all the time. I have never restored my phone or done any other sort of maintenance to my phone in two years of ownership.

I just don't understand how folk's experiences with their iphones can vary so much! Perhaps the moral of the story is that we can't always judge what our phones will be like from articles, forum posts, etc. We just have to try it for ourselves and cross fingers firmly.

Having said that I'm sticking to v3.1.3 on the 3G. Two many horror stories for me, and besides the iphone 4 is calling me to buy 😉

Field test mode is back in 4.1.

Dial 3001#12345# and press CALL. Your antenna bars will switch to negative numbers - more negative is worse. I forget, but I think one site reported that -50 is about the best you can get and that -113 is what the 3G phone could still maintain a call with, but the iphone 4 could go to -120.

It takes a few seconds after the field test screen comes up for the numbers to show. Now I can do some periodic testing in places I normally call from and have some base figures.

I personally wish you could keep the numbers permanently, but when you press the home button, you are back to the bars.
