Hi all

I note that there are several topics in the forums asking about the benefits of one particular phone over another, but no-one seems to ask from the point of view I am interested in.  Specifically, what are the actual requirements that people have for a mobile handset?  My list, in order of relative importance, is below.  I have not yet found a handset that meets all of these requirements and I don't actually expect that I will achieve handset nirvana, but I am looking for something that has most of the following capabilities:

1) send/receive txt/phone/pxt messages
2) use as an internet connection for an iPad (tethering via either Bluetooth or WiFi)
3) a decent battery life (e.g. at least two days of txt/phone use between charging)
4) a camera (front facing is not necessary)
5) removable media (e.g. a micro SD card)
6) back-up/synchronise content so if the phone is broken I can still see my files/music/pictures/movies/txts/contacts/list of apps/etc.
7) GPS capable
8) ability to add apps
9) ability to remove bundled apps I have no use for (a bugbear I have with my current phone)
10) ability to listen to radio with and without headphones (either via a built-in receiver or an internet-connected app)
11) ability to update the OS (my current phone does not permit this so I’m stuck with an old version of Android)
12) 4G capable, but with the ability to select 2G to reduce battery usage
13) a small handset (ideally no bigger than a Nokia C5 - if possible)
14) physical keypad buttons (either qwerty or numeric, a slide-out keyboard would be acceptable)

Having used Palm/CE/Windows Mobile/Symbian/Android/iOS over the years, I have no particular preference.  I am open to Android, Windows, iOS, Symbian, NokiaX, Blackberry or any other platform that is likely to have ongoing support for the next 2 years - as long as the combination of the phone and the OS meet most of the above requirements.  Am I being unrealistic?  Is there any phone on the market like this?

I am more concerned about the capabilities of the phone itself than I am my mobile provider.  My business plan is currently a Vodafone post-pay, but I am off contract and looking at my options before deciding who to sign up with for the next couple of years.

tl;dr...Does anyone make a 4G Nokia C5 with tethering?

Cheers
Christopher
