I will upgrade my stock ICS 4.0.3 to JB when that is released to my Samsung S2. But the problem is that I have removed a lot of bloatware on my phone like Game Hub, Music Hub but also the stock-clock (and more) with Titanium Backup. But will that cause a conflict with Jelly Bean when JB is being installed? The system is missing files and apps, and then JB is installed on top of that. Sounds like a setup for problems to me. Anybody tried JB with uninstalled stock-apps on their old ICS?
