I am using opera 10 Beta 2U, and I am not having these issues on my diamond.
- I have had no memory issues, maybe using a program like memaid might help you free up some space.
- if you have the "turbo" option selected, graphics may show up pixelated.
- I don't use OZim so i cannot help you there
- mobile redirects happen on every device, and every browser. sorry
- by sending messages to you mean using the myspace IM option, or just sending someone a PM? if its just sending a PM, you can do that easily through the mobile site. as for tagged.com, i don't use that site, so i cannot offer a solution.
- I have no idea why you're having this issue, i have never had a problem with using the keyboard on opera mobile. Maybe someone using the same phone/ROM would be able to shed a little more light on it.
No browser is perfect, and Opera is still in Beta, so it's bound to have some bugs. Luckily you don't have to give them any money, as they are offering it to the public for free. One of the reasons they do this is to get feedback on what to fix, and what features the consumer wants. so if these are issues you would like fixed in the next version, I'm sure opera would love to hear from you. It allows them to develop a better product, and thats good for everyone. Go here to reports bugs:
