Edit : Solved - I was expecting a bahvior which is different from the designed one. If one select Auto Connect to any connection type or gprs or wifi, the phone will connect at the set interval below, regardless of internet requirement.
This means that the phone will connect even if no app needs internet.
I have my network connectibity set to Auto Connect to Any COnnection, I like it this way, and using auto disconnect to close those connections when not needed.
The problem is, every 5 minutes or so, my phone connects to 3g internet if there is no wifi. Some app is causing it to connect.
I have tried using tcpdump in if-up.d/ but the cap was empty.
I verified my tcpdump is working by browsing some site manually, and that did appear in the pcap file.
in settings . internet connection. do you have it to auto connect?just a guess?
The OP does say that he has it set up that way.
First off, check the most obvious apps, ForecaWeather, OMWeather, RSS accounts (if any are set up), Desktop news widgets etc.
Next go through your apps. Check the ones that were last updated, as sometimes they will revert to default settings after an update. Then check any positioning mapping apps that you've got installed.
It's just a case of going through everything to find the culprit.
As an afterthought, why hasn't Nokia caught on to this and changed the connection request to say something like "Suchanapp is requesting a data connection"
It's something that's always bugged me.

I don't have any :
Foreca, OMWeather, RSS Accounts
IM Accounts are disabled
No Desktop news apps.
No Positioning apps running and actulaly not even installed
I tried looking at top, ps, practically starring at them, using diffs, i'm going crazy!!!!
And yes, just give me the process ID and i'll be happy ):
@ste-phan and handaxe
Iv'e tried both tcpdump on the phone and netstat -a on the phone.
Tcpdump showed no traffic - this can be reasonable only if it starts too late, which I don't believe is the case.
netstat -a only showed connections to my PC (ssh) and connections to localhost, i.e. source = dest = n900.
I have ddwrt on my wifi router, and the model is linksys wrt54g2, sadly tomato doesn't fit it...
I'll try and run tcpdump on ddwrt, though I don't know if I can.
Sniffing and looking for tcp / udp sessions so far didn't reveal any info at all...

Is this a tcp connection? does it remain Established for long? or just a sec?
Isn't it contradictory to configure autoconnect and install autodisconnect ?
As far as I understand autoconnect, it means to automatically
connect if a network (GPRS and/or WIFI) is available and
not only if a connection is requested.

You think? why would the phone maintain a connection if it's not needed! it's just a battery drain!
To me it sounds like :
- If phone needs internet, autoconnect will connect via wifi or gprs/3g
- If the internet is idle, autodisconnect will drop the connection.
- Sounds perfect to me. If you think autoconnect just brings up a connection cause there is none at the moment then this is probably my problem.
