Hotmail - browser not supported

[jj14x]

Hello, I'm using the stock Sprint 6.5 ROM on my TP2 and since yesterday, I noticed that I am no longer able to use my IE (or opera) to access my hotmail account (I have two hotmail accts - one is connected using pocket outlook, and I usually use IE to access hotmail.com for the second one - both used to work till a couple of days ago).

Now, when I browse to hotmail.com, and enter my ID/pwd, I get a "Browser not supported" message (on IE and on Opera) - I usually use "browse websites as mobile device" option on both (I tried switching this option, but that didn't do anything)

Has anybody else seen this probem? Any suggestions?
