Sony Ericsson :: W580i - Email Client / No Mark All Option

I am new to this community and I am here because of the problems I experienced with my W580i today and yesterday. Yesterday I finished setting up the phone's email client and got it working but then the trouble began. I went to my 'Inbox' and chose 'Send & receive' to download emails from the server and after few minutes I got the result -- 300 (if I recall) unread emails. 50 of them were displayed on the first page and all had yellow closed envelope tags. Now the problem was that actually all those emails had already been read using my laptop's email client but that's just the beginning. So, I read all those messages again (yes, I know I can mark them read one by one), which took some time.

But after that I still had 250 or so "unread" emails, so I chose 'View older' to get rid of all unread emails and obviously had to download all those messages, which takes about 5 minutes alone. Here's where it got really bad. I had noticed that it was possible to mark messages but when I hoped to mark all 50 messages together and 'Mark as read' I found out for my sadness that it is not possible to mark more than one message read. Thing is that group of marked marked messages can be marked for deletion but not marked as read. That meant I had to mark all 50 messages on the page as read one by one and that takes about 4 minutes when you do it fast. Now that's bad but it got much worse.

(Also a note that messages that were on 2nd and other pages weren't tagged with yellow envelope but grey one and I think they had to be downloaded again to open after clicking them, which different them from the yellow ones, which can be opened straight away. At least it seemed to be so.) So, I went on to next page (, which obviously meant I had to download all those messages) and marked those as read but soon I realised that messages marked as read on previous pages will automatically be unread again when you go to next pages (select 'View older'), which is obviously very annoying! Well, I am not the type who would give up, so I tried all kind of things like choosing 'Send & receive' again and starting from the last page of "unread" emails, which meant 6th page.

I had some luck with the latter as when I had marked last (page 6) 50 messages all read one by one and went on to 'View newer' (page 5), those messages had still remained read and number of unread messages had decreased by 50. So, I was quite hopeful and went on to next page ('View newer' again) and number of unread messages was 200 (wow) ! But after managing to deal with all those messages on the page and going on to next page number of unread messages had automatically gone up again. I was obviously rather sad now as my plan didn't work but still didn't give up. But fortunately/unfortunately my suffering was finished as I ran out of credit (I'm using pay as you go service), which is probably quite obvious after downloading pages with 50 emails many times.

Anyway, that's the worst thing that could happen to me as I had just topped up my mobile 2 days ago and I normally manage at least 2-3 months with one topping up! As I am poor at the moment I can't afford topping up again so soon either. Plus I have spent many hours on this annoying thing yesterday and today (because I had to repeat the steps I mentioned above, battery ran low etc.). Now, my first question is whether there is any way to avoid that kind of trouble and somehow get all messages read? My experience shows that it doesn't seem to be possible. Secondly, maybe just maybe only way would be to delete all those so-called unread emails? But then I would get them again when choosing 'Send & receive' to get new emails? Thirdly, I am so disappointed that I would like to get re-imbursed by Sony Ericsson but that's probably unthinkable as you didn't make me use the email client.
