I do not mind that you update the firmware on my phone BUT I DO MIND IT when you mess with the firmware on my phone and I do not have the choice to reject the PUSH. This last push has cost me several hours of time. Please leave me alone.
The update isnt being sent just to you so dont take it personal. The update is usually bug fixes that users demanded get fix and if this is a issue for you you may be able to contact CS and request them to disable the push option in the network and see if they are open to do this but remember that this will stop all future updates being sent to your device.
Also I have to ask since the update usually doesnt wipe a device, how does recieving a update cost you hours of time?
I dont think the stock browser has this option but I am using Opera Mobile and this option is availiable and also there is a number of other apps on market that adds this feature..
