IOS 4.1 and Baseband 2.10.4

[Kippei]

So I went to the Apple Store locally today to have my iPhone 4 examined for the post iOS 4.1 battery drain and heat issue.
It took about 90 seconds for them to identify an issue and replace my phone. Apparently the 4.1 update changes the modem software rev and actually creates a background process that is unnamed and never stops. It's a bug apparently.
My iPhone 4 was one of the original 600,000 sold on day one. In fact, mine was delivered the day before the release. I am thinking the first phones might be more susceptible to this.
So, the replacement is running 4.0.2 and the older modem FW rev and is absolutely wonderful again. No 4.1 until this issue is resolved.
Point is, there is an actual issue with SOME of the phones, so don't let anyone tell you you're wrong and you shouldn't have to disable ANYTHING to use your phone normally.
The guys at my local store were very helpful and interested in this issue.

Anyway, if you're troubled by the battery drain, take your phone back and let them try to identify if yours is affected. After all, if we want the bugs fixed, we need to let them know and this forum really won't do that.

update to 4.1 using tiny umbrella and stay at 1.59.00 then you have the best of both worlds

Well, for those unaware of this issue, I assume future firmware updates will fix this issue. In the mean time someone on Cydia might be able to patch this, like the previous PDF patch; for those affected.
