Huawei Ascend G330 U8825-1 resize internal partitions to gain space for apps

the g330 comes with a reasonable storage. But there is not enough space for apps on /data. The internal sd-card got a lot of space. resizing /data (part. 18) may be critical and requires another recovery image. So my idea is to log in the phone, start fdisk /dev/block/mmcblk0, delete internal sd-card partition (19), then create a e.g. 1 GB partition with ext4, which I will mount on /data/app, and give the rest to a new partition 20 for internal sd-card.

I think this approach is more fail-save and can be done quite fast. I have to change just init.rc to add one mount and vold.fstab. Has somebody tried this?

yes, i know, the dalvik-cache and /data/data will still load the /data partition, and app2sd would save the same space from /data. But app2sd needs one mount for each app (at least in GB), so booting takes very long time and I have to wait until I can launch an app.

I read sometimes, the kernel get the offsets of the partitions of flash as parameters when booted - so some offsets would be wrong when I change the partion table. This would cause to fail mount /data/app - what about this?
