Yes, for example I'm running 42-11 release and my "record" uptime is 17 days after which I rebooted the device by myself due to something I don't remember..

Italy
TIM SIM (128k)
Not a single reboot in 8 days.

just sent a question to the online store and asked if i could get a replacement. because it strongly seems hardware related atleast for now.

Question: does everyone of us having this issue installed Foreca Weather widget? If yes try uninstalling it and let us know.

Yup, that's pretty much the way it works with any product.

In any manufacturing run, it is inevitable that some devices will be faulty and some of these faulty units slip through QA at the factory. Unfortunately, they are all packed into identical looking boxes and the retailers do not separate them into faulty and non-faulty stock-lines.

Have anyone got a replacement?

I can't hold this way anymore.

Not had a reboot yet. 3 days and counting of running. Will update this post when I get my first one.
The only program I have installed then decided to uninstall is AP news, seemed to be a little greedy using the internet.
I am using OMweather as it seems better put together than Foreca.

just got my n900 3 days ago, first night i had 7 reboots the next day 15 reboots,the next day got 11 reboots..finally on the third day of my n900 in my hand i brought it back to nokia store here in Dubai where i bought it,immediately they change it (got a replacement)..i ask the sales manger if they had similar cases as mine,they told me they had only once and im the second one..fortunately the first costumer w/c had the same problem did not come back or call on the store for another replacement (it means that the replacement that he got is working fine).. so for mine its working fine for now got no reboots..maybe this is a hardware problem,just my thought..anyway just sharing my experience so far with my device..(note if u bought your device on nokia store you have seven days to exchange it if its not working fine..beyond seven days you'll have to send it at nokia care center) Thanks to NOKIA!!!

I requested a replacement or refund since I have it for a week only. Let's see how it ends

HI guys, I just received my N900 today in Kuwait, and unfortunately I've had more than 10 reboots in a span of 5 hours. It mainly reboots when it has to do some heavy processing or loading, very very annoying issue I hope there is a fix to.
