what does that mean when it is blinking and such?
I have a hunch that it means that i am accessing internet or something.
I dont have a data plan so am i getting charged whenever it appears?

I don't know whether you are getting charged or not--thats between you and ypu carrrier, but the arrows do indicate the BB communivating with the network. If you look real close, I believe the larger arrows are data movement and thge smaller arrows are simply the phone communicating with the carrier.

They're the same size, but usually both up and down arrows go on and off together with GSM interaction. With data they will randomly cycle through up, down, or both.

I read someplace they indicate data going in and out of your berry depending on direction. Also i'm pretty sure your not getting charged as the arrows are also present when you range to use phone or your data connection changes depending on your location.

Yeah, it is the data, charges are depending on your service. Do you have unlimited data plan? If you do, then most likely you are fine, unless you are tethering on a Cingular provider.

Nope.. It means your phone is updating service or your receiving data messages or a call..

Peter, if you look real close and don't BLINK, you can see the smaller arrows (almost 1/4 the size of the data arrows) in the same corner. Maybe yours doesn't, mine do, both 8700 on TMo, and 8800 on Cingular. Look especially if you turn on Wireless, you will see the smaller arrows between 'gprs' to 'edge' to 'EDGE".

I'm not delusional. The arrows I speak of are very certainly different sizes.

It does the same thing on my 7130e so you’re not delusional at least not because of this. I am curious though without a data plan has anyone actually been charged or had their minutes used up because of the connection.
Also from my experience if you don't have data then you don't have the internet icon, so you should not be able to access the internet is this correct?

Some users have reported they can get limited internet via Opera Mini and setting the APN at the TCP edit. It is not universal on any carrier.
