I have since moved over to 2degrees as twitter was about the only thing I had left on Vodafone, txt prices are just too high (for a low user like me, i have no plan to send 1000-2000 txts).
Just 2 days ago I put in my old Vodafone SIM card and I got 4-6 fairly new twitters appear on the phone and I thought oh YAY they fixed it. Hehe nop, I was wrong, they where the only new twitters I got for the whole weekend (and yes I did get new twitters when I checked my twitter account, they just never came to my phone).
So now im back to my 2degrees SIM :) (wish my phone had two SIM card slots

Anyone else having similar issues...resolutions...?
