I have just recently started to use 3’s HSDPA mobile broadband service, it is most impressive and speeds, while as expected seldom reach the advertised 3.6Mbps, but this is not unexpected with mobile services, coverage is never perfect, I have however achieved speeds of up to 2.4Mbps in and around Limerick city centre, Dublin is well covered also I have found so far. The sweetest part is the train routes are relatively well covered, i.e. adequate to do some work at a decent connection speed.
