WM PDA / phone with best WLAN range

Hi

New to PDA's and I recently bought a MWg Atom Life - I have to say that the WLAN range is dreadful
My Nokie E51 has 2 out of 3 bars for a certain Network and from the exact same sport, the Atom Life only got 1 out of 4 !!

I then tried it on my own WLAN at home and router is upstairs. Atom Life gets
4 out of 4 bars beside the router. Go downstairs and it drops to 2 out of 4. In back garden and it's 1 out of 4 but doesn't connect. E51 still has 3 out of 3 bars !

So, I don't want to be put off my first venture into PDA's - can someone recommend me a WM phone which has great WLAN range ? Essentials - WM and IE. Nice to have would be a radio

TIA
Rob
