Is flashing rom ok?

[se7en20]

I haven't tried flashing rom. I just want to know if it's ok to flash instead of waiting for ota update. What are the cons, if any, if I use a rom from other countries? Any disadvantages of flashing?

Lumia black is really taking so long here in our country, still waiting for approval up to now. It's not that I'm losing patience. I'm just concerned about my power button which seems to be a little worn out and I feel like it's getting worse every time I wake up the phone. I badly need dttw and the new glance. Thanks.

It's totally OK to flash a ROM, but you will lose all your data, make sure you backup your phone before flashing.

Thanks! Will I also lose apps and purchases?

When I flashed my phone, all apps were restored/reinstalled, but I'm not sure if you'll lose purchased apps, because I never purchased an app myself.

Thanks a lot! I guess I'll give flashing a try.
