If I use 3G it works fine, if I use a 3G card in a WiFi router (telecom XT) then it streams fine - but if I connect through WiFi to mu Slingshot ADSL then whilst the site loads and you can get a track list, none of the streams will play
this is really frustrating - more so by the fact that the same site html5.grooveshark.com works fine from my laptop - so it's not the site or ISP per se, and it's not the IOS devices - it's just IOS devices through slingshot!
anyone offer any advice? Note I've posted here as it appears to be ISP specific (no problems on Telecom XT - or Telecom ADSL)
(oh I've tried both the safari and chrome browsers on IOS)
