Current state of play re. UK data plan pricing and advice re. 3 vs T-Mobile data access please!

Hi

My current O2 contract is coming to an end and I'm going to be moving
to a K850i - I've got a K800i just now and I like SE, but even better
the K850i has HSDPA support

I'm therefore looking for a reasonable data plan (something that
couldn't be said for O2 in the past year). I've looked at the current
deals on offer (see below) and it looks like it's down to T-Mobile and
Three (for my usage pattern at least - I want both mobile and mobile-
as-modem use (including ability to use Slingbox) and my voice/text
needs are around the 300/50 level per month).

The main thing I was wondering was - does anyone have any first hand
experience of 3 vs. T-Mobile's data services? For the past couple of
months I'd been assuming I'd be going with WnW Plus but the new 3
plans look fairly good - slightly more expensive (£2.50/mo) than T-
Mobile's, but less restrictive usage (I think!) with possibly better
HSDPA coverage and slightly faster access speeds (3.6Mbps vs.
1.8Mbps). Any problems with blocked ports on either service?

Would be very interested to hear people's views.

Cheers

Alan

In central London I get max speed of 450Kbps connection (tried in
about four locaitons) which appears to be for upload and dowload
speeds on T-Mobile WnW Pro using a Nokia 6120 classic as a modem.

I went into a T-Mobile store to ask if HSDPA was enabled and they said
it should be and it is a limitation of the phone that I'm not getting
closer to 1M and that I should get a data card for faster laptop
access.
I called up customer services and they did not have an option to
enable HSDPA against my subsription (Flext £15pm tariff).
According to the Nokia manual I should see a 3.5G icon when connected
at HSDPA speed, but I've only ever seen 3G or GPRS.

All in all I'm a bit disappointed by the modem performance.

With Three you'd have the option of using the 3G USB modem (excluding
the modem cost) for the same price as adding the modem capability to
your phone, which might be a bit more flexible.
